varchar.diff
|
||||
------------
|
||||
This patch was necessary for the OpenLink Postgres Database Agent.
|
||||
I think this fixes a bug anyway.
|
||||
|
||||
The following query demonstrates this bug:
|
||||
|
||||
create table foo (bar varchar);
|
||||
insert into foo values (''); -- no problem
|
||||
select * from foo where bar = ''; -- fails
|
||||
|
||||
|
||||
fsync.diff
|
||||
----------
|
||||
This patch adds an option to disable synchronous writes.
|
||||
It adds an extra option to postgres: -F
|
||||
|
||||
When started with -F, all fsync() calls will be no-ops,
|
||||
so you'll be in big trouble when your machine suddenly crashes and your disk
|
||||
cache is not flushed.
|
||||
|
||||
Use at your own risk (but it is *much* faster with large inserts)
|
||||
|
||||
This also speeds up initdb for initial database bootstrapping
|
||||
|
||||
To start postmaster with this "feature" enabled, type
|
||||
postmaster -o -F -S
